data.edit.wl interpolates a set of scatterings or absorptions at a source set of wavelengths to a target set of wavelengths. It attempts to infer the source and target wavelengths from the names given.

By default it will attempt to adjust any inputs it is given to the TSI Neph wavelengths (R, G, and B in symbolic names).

There are two modes of operation, the first is the fully automatic mode used from within the environment set up by data.edit.get. The second is manual invocation.

Set a fixed angstrom exponent to use when interpolation or extrapolation is not possible. The limit is a fraction of the original wavelength that defines how far the extrapolation is valid for. For example the default of 0.1 applied to 530 nm gives a valid range of 477 to 583nm. Setting the limit to zero allows for unlimited extrapolation.
